Answer:
The numbers are approximately: 4.000 and 1.000
Step-by-step explanation:
The given parameters can be expressed as:
[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]
[tex]\frac{x}{1000} - \frac{y}{1000} \approx 3[/tex]
Required
Determine the numbers
In each of the equations, multiply by 1000
[tex]1000 * [\frac{x}{1000} + \frac{y}{1000} \approx 5][/tex]
[tex]x + y \approx 5000[/tex]
[tex]1000 * [\frac{x}{1000} - \frac{y}{1000} \approx 3][/tex]
[tex]x-y \approx 3000[/tex]
So, we have:
[tex]x + y \approx 5000[/tex]
[tex]x-y \approx 3000[/tex]
Add the two equations
[tex]x + x + y - y \approx 5000 + 3000[/tex]
[tex]2x \approx 8000[/tex]
Solve for x
[tex]x \approx 8000/2[/tex]
[tex]x \approx 4000[/tex]
Substitute [tex]x \approx 4000[/tex] in [tex]x + y \approx 5000[/tex]
[tex]4000 + y \approx 5000[/tex]
[tex]y \approx 5000 - 4000[/tex]
[tex]y \approx 1000[/tex]
Using:
[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]
We have:
[tex]\frac{4000}{1000} + \frac{1000}{1000} \approx 5[/tex]
[tex]4.000 + 1.000 \approx5[/tex]
This implies that, the numbers approximates to 4.000 and 1.000, respectively.

Answer:
it's 8
Step-by-step explanation:
(10×1/5)^3=2^3=8
Answer:
The answer is 8!
Step-by-step explanation:
Subtract the like terms. As you can see, the 10 in the numerator and denominator have the same base. Therefore, you can subtract the exponents, which would be 10^1, or 10. You would do the same for 5, which would be 5^-1, or 1/5. You would then make this one fraction, the 10 and 5. The fraction would be 10/5, or 2 once simplified. Now, don't forget the outside parentheses! You would do 2^3, and your final answer would be 8. Hope this helps!

10) 50° (supplementary to 130°, 180° - 130° = 50°)
11) 130° (alternate exterior to 130°)
12) 130° (vertical to 130°)
Step-by-step explanation:
Val measures the diameter of a ball as 6 inches. How many cubic inches of air does this ball hold, to the nearest tenth? Use 3.14 for π.
Answer:
The ball holds 113.0 cubic inches of air
Step-by-step explanation:
Firstly we need to know the shape of the ball
A ball is spherical in shape
So to know the number of cubic inches, we have to find the volume of air in the ball
Mathematically, we can do this by finding the volume of the ball using the formula for the volume of a sphere
The formula for the volume of a sphere is ;
V = 4/3 * pi * r^3
in this case, r = d/2 = 6 /2 = 3 inches
where r is the radius of the ball and d is the diameter of the ball
So, substituting these values , we have
V = 4/3 * 3.14 * 3^3 = 113.0 cubic inches
Which of these tables represents a function?
Answer:
Table W represents a function
Step-by-step explanation:
Mathematically, for us to have a function , no two y-values can take a single x value
But it is possible that two x-values have a single y value
So let us make a selection from the table
We have the correct option as;
W
What is the range of possible sizes for side x
Answer:
0.5 < x < 16.5
Step-by-step explanation:
For a triangle (by the triangular inequality theorem), we know that the sum of any two sides must be larger than the other side.
When we have a triangle and we know two sides, let's define the measures of these sides as S1 and S2. (such that S2 > S1)
By the first property, we will have that S1 + S2 > S3
Where S3 is the third side, the one that we do not know.
But there is also a lower restriction, given by:
S2 - S1 < S3 < S1 + S2
This is because we also must have:
S1 + S3 > S2
and
S2 + S3 > S1
We can rewrite both of these to get:
S2 - S1 < S3
S1 - S2 < S3
Because S2 > S1, the first inequality is more restrictive, so we need to use that one.
Then we get the inequality:
S2 - S1 < S3 < S1 + S2
Ok, in this case, the shorter side is 8.0 then:
S1 = 8.0
And the longer side is 8.5, then:
S2 = 8.5
And the third side is x, S3 = x
Replacing those in our inequality, we get:
8.5 - 8.0 < x < 8.5 + 8.0
0.5 < x < 16.5
This is the range of possible sizes for side x.
Solve for x

The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation.
A. 1/150 dollars per day; the cost is $1 for 150 days.
B. 25/1 dollars per day; the cost is $25 for each day.
C. 1/25 dollars per day; the cost is $25 for each day.
D. 75/1 dollars per day; the cost is $75 for each day.
Answer:
B
Step-by-step explanation:
75 divided by 3 = 25
so 25 dollars each day
Answer:
B. 25/1 dollars per day; the cost is $25 for each day.

Can someone plz help me with this one problem!!!
Answer:
Step-by-step explanation:
Answer:
v = 9 m
Step-by-step explanation:
the formula for the perimeter is P = 2W + 2L.
Here the perimeter is 42 m = 2(12 m) + 2v. Solving for 2v, we get:
42 m - 24 m = 2v, or
v = 21 m - 12 m, or
v = 9 m
What is the volume of a cylinder that has the following measurements?
area of each base: 50.24 ft2
area of lateral surface: 75.36 ft2
height of cylinder: 3 ft
128.6 ft 3
226.08 ft 3
150.72 ft 3
175.84 ft 3
bad answers will get banned good answers will get brainlist please
Volume of a cylinder = area of base x height:
50.24 x 3 = 150.72 ft^3
Answer:
150 ft³
Step-by-step explanation:
base = circle..................base area = area of the circle = πr².
to get the radius of the circle, we substitute from the formula.
let π be 3.142
3.142 × r² = 50.24.............................. 3.142r² = 50.24
divide both sides by 3.142 to get r² = 15.99....................find the square root of 15.99 to get r = 3.999.
VOLUME = πr²h
= 3.142 × 3.999 ×3.999 × 3 = 150.72 ft³
This is another way of doing it.

Answer:
Angle 5 = 37°
Angle 8 = 143°
Step-by-step explanation:
Angle 2 = Angle 8
Reason : Alternate exterior angles are equal.
Therefore,
Angle 8 = 143°
Angle 5 + Angle 8 = 180°
Reason : Angle 5 & 8 are in a linear pair.
Angle 5 + 143° = 180°
Angle 5 = ( 180 - 143 )°
Angle 5 = 37°

Step-by-step explanation:
Answer:
I’m pretty sure the answer is 56 in^2
If I’m wrong I’m sorry. I’m not strong on this.
helppppppppppppppppppp
Answer:
vertical opposite angles are always equal
= 143°
co-interior angles are supplementary ( 180° )
∴ x = 180 - 143 = 37
∴ x = 37°

Answer:
12, 2 and 10
Step-by-step explanation:
(1)
b - 4 = 8 ( add 4 to both sides )
b = 12
(2)
y + 7 = 9 ( subtract 7 from both sides )
y = 2
(3)
16 = n + 6 ( subtract 6 from both sides )
10 = n
